Embodiment I~V, comparative example I -1, comparative example I -2, comparative example I -3 and comparative example I -4,
UV solidification coating and graphite radiating material are prepared by the formula and experiment condition of table 2, product 1~5,1 '~4 ' is respectively obtained, makes
Preparation Method is as follows：
(1) UV solidification coating is prepared：Coating material solidified P1~the P5 of UV, P ' 1~P ' 4 are equably coated with by automatic coating machine
On base material, application rate is 10~30mm/s；
(2) UV solidifies：The coating of step (2) is put into uv curing machine and enters photocuring, sample rate is 1~10m/
Min, light intensity is 280~420mW/cm2, hardening time is 5~50s.
The base material is artificial graphite flake or natural graphite flakes；The size of the graphite flake is not required particularly.
Contrast for convenience, in embodiment and comparative example, all base materials use electrographite piece, the length of graphite flake
Spend for 15cm, width is 8cm, thickness is 25 μm, and the cated thickness of institute is 10 μm.
Note：The UV solidification coating of the present invention is using graphite flake as base material, and graphite radiating material then includes graphite flake and base material,
Therefore, product 1~5,1 '~4 ' can both refer to UV solidification coating, can also refer to graphite radiating material.
Table 2 prepares the formula and experiment condition of UV solidification coating and graphite radiating material
The performance of the UV solidification coating of table 3
Note：△ refers to coating under R5/180 ° of test condition, and bent more than 10000 times, pliability is good；▲ refer to coating
Under R5/180 ° of test condition, it is impossible to bend 10000 times, pliability is poor.
Zero refers to the breakdown voltage resistant ＜ 1000V of coating, poor insulativity；● refer to breakdown voltage resistant >=1000V of coating；
0 grade shows coating without coming off, and 1 grade shows that 0~5%, 2 grades of coating shedding shows 5~15%, 3 grades of tables of coating shedding
Bright coating shedding 15~35%, higher grade, shows that the adhesive force of coating and base material is poorer.
As known from Table 3, when coating includes the aliphatic PUA oligomer and glycols diacrylate of bifunctionality
When, such as embodiment I and II, coating has excellent pliability, bending resistance, electric-breakdown resistance, wearability and adhesive force, with
And relatively low shrinkage factor.Coating prepared by the aliphatic PUA oligomer of single functionality has good pliability and bending resistance,
But its wearability and electric-breakdown resistance are poor, such as embodiment III；The aliphatic PUA oligomer or aromatic series PUA of polyfunctionality
Coating prepared by oligomer has certain pliability, but its bending resistance is poor, such as embodiment IV and V；Epoxy acrylate
Pliability, bending resistance and the adhesive force of the coating prepared with unsaturated polyester (UP) are poor, such as comparative example I -1 and I -2；When
Coating be free of reactive diluent (2) when, or reactive diluent (2) be single functionality 2- phenoxyethyl acrylates when,
Such as comparative example I -3 or comparative example I -4, coating has a good pliability and bending resistance, but its wearability and
Electric-breakdown resistance extreme difference.Correspondingly, in embodiment, graphite radiating material of the invention has excellent bending resistance, resistance to
Voltage breakdown, wearability and pliability.
In addition, applicant has found in an experiment, when coating material solidified identical, UV solidification coating the thickness of formula of UV in embodiment
Spend for 5~30 μm when, its properties and table 3 are consistent, meet use requirement；When reactive diluent (3) includes methacrylic acid
When one or both of hydroxyl ethyl ester, hydroxy propyl methacrylate, methacrylic acid tetrahydro furfuryl ester, it can reach and embodiment
Identical effect.When from natural graphite flakes as base material, its effect and electrographite piece are essentially identical；The present invention is to graphite
The length and width of piece is not required particularly, when the thickness of graphite flake is 17~40 μm, can be reached identical with embodiment
Effect.
